Looks to me like an overdose was the culprit, not the water.
Have you checked for the Fox Farms Weekly Feeding Schedule for soil, or are you trying to use the bottle directions? Quite a a few companies that list bottle directions assume it's used as a stand-alone nutrient. This can and will adversely affect your ladies. No need for the soluables they list on the feeding schedule, until you are experienced enough to recognize the issues that their use will bring. The 'Trio' works pretty darned good if you follow directions. With the Trio, mid-way through flowering you'll want to add the molasses or CalMag Plus at standard dilution, while lowering or discontinuing the Big Bloom.

Sorry...I'm not a believer that you need to worry about TDS ppm's if you're in soil. How many ppm's exist in a gallon of potting soil? And since you are trying to lower the ppm's of water, shouldn't you guy's be just as worried about the TDS ppm's of the soil you're in...? From my years of experience in the online cannabis community, this all started with a concept for watering/feeding hydro plants, and has 'morphed' into a need for soil growing, too. But...I'm just not buyin' it for soil grows.

Feel free to show data and prove me wrong though. :thumbsup:
